Case Type   : 多节点写入
Case Name   : 备机子事务测试，savepoint,rollback to savepoint,提交，事务内的读也会转发到主
Create At   : 2023/07/20
Owner       : opentestcase033
Description :
    1.修改enable_remote_execute参数值为on
    2.创建测试表
    3.备机开启事务，insert，savepoint, rollback to savepoint 提交事务
    4.查询表的内容
    5.查看主机日志
Expect      :
    1.修改成功
    2.执行成功
    3.成功
    4.成功
    5.事务中读写均转发到主机
